This invention relates to mine cars. An object of the invention is toprovide an improved car for use on mine railroads.

A further object of the invention is to pro- 55 vide a car of thecharacter described in which several parts thereof are separable forpacking, and for facilitating assembly.

A still further object of the invention is to provide an improved car ofthe character described, having a novel sanding mechanism.

A further object of the invention is to provide an improved car of thecharacter described having a novel braking means.

Another object of my invention is toprovide a car construction of thecharacter described,

which shall be comparatively simple in construction and manufacture andpractical and eflicient in operation to a high degree.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of ele-.

ments, and arrangement of parts which will be exemplified in theconstruction hereinafter described, and of which the scope ofapplication will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the variouspossible illustrative embodiments of this invention,

Fig. 1 is a bottom plan view of the car, showing the assembly of wheels,and the sanding and braking devices.

Fig. 2 is a side elevational view of a car embodying the invention.

Fig. 3 is an end elevational view of the car, illustrating details ofthe car construction.

Fig. 4 is a partial longitudinal sectional '40 view of the car body,with a wall removed.

manner hereinafter described. The body 12 is formed of two side walls18, and end wall 20, and a front wall 22, all detachably assembled, ashereinafter appears. Carriage 14 has associated therewith, the sanding,device 24 and the braking device 26 mounted cooperatively with thewheels 16.

The side walls 18 are formed in a manner similar to the wall 20, as seenfrom Fig. 5, of a plate 28, having secured at one end thereof thechannel 30, the depending flanges 32 of said channel being spaced fromthe end 34 of plate 28 by means of the blocks 36, 38, all fixed inrelation to each other by the rivets 40. The bars 42 are riveted as at44 along the vertical edges of said plate, said bars extending beyondthe bottom end 46 of plate 28 for a purpose hereinafter appearing.

The bottom 48 of the car is made up of the plate 50, flanged at thesides 52, 54, and having the end flange 56 riveted thereto. Butting upagainst the edge of end flange 56 is a chan nel 58, through the innerportion of which is received a strap 60, all these parts being securedremovably to bottom 48 by means of bolts and nuts 62. Said straps areU-shaped, the arms of the U extending up from the edges of bottom 48,and being adapted to receive in contact therewith the plates 28 of sidewalls 18, bolts 64 passing through openings in said strap and beingsecured through aligned openings in said plate by nuts 70. A number ofstraps of this type are spaced along bottom 48 and side walls 18 inorder to securely, but removably, position the side walls 18 withrelation to the bottom 48.

A channel member 7 2 is riveted to the rear end of each side wall, a bar7 4 being retained in the hollow of said member by means of the rivetssecuring member 72 to side wall 18. By this means, groove 76 is providedinto which the plate 28 of end wall 20 is adapted to be received, thebar 42 being received in contact with bar 74, and with the flanged edge7 8 of channel 7 2.

Extending along bottom 48 parallel to side walls 18, but spaced from theside edges of bottom 48, is a bar 80. The spacing is sufficient toreceive the ends of plates 28 of side Walls 18. A similar bar 82 extendsparallel to the rear edge 84 of bottom 48. Bars and 82 are cut short atthe corners of bottom 48 to snugly receive the depending end of the bars42 secured to plate 28, thus positively positioning the walls withrelation to each other.

The front wall 22 is adapted to be assembled with the side walls 18 in amanner similar to end wall 20, said front wall 22 being formed with apivoted wall 86 to provide an opening 88 through which the car may be.

cleaned. A suitable latching device 90 is embodied to secure said wallagainstmove ment except when desired, and is seen to consist of pivotedarm 92, having bolts 94, 96, pivotally secured thereto on either side ofthe pivot point and slida-bly retained against movement by guides 98. Onoperation of arm 92, these bolts will be extended into notches in endportions 102 of said front wall. If desired, this latching mechanism maybe encased, as is preferable, by sheet 104 applied to the front wall.

Detachably secured by bolts 106 to the one side wall 18 and to the edgeof front wall 22 is a bracket 108. Said bracket forms one bearing 110for the shaft 112, which passes through another bearing 114, carried ona bracket 116, similar to bracket 108. A bevel gear 118 is secured onthe end of shaft 112 and meshes with another bevel gar 120, carried onthe end of a shaft 122, supported in bearings 124, detachably secured tobottom 48, in any well known manner. A. set of bevel gears connoctsshaft122 with the longitudinal shaft 12'? carried in bearings 129 secured tobottom 48. Shaft 127. is threaded at end 126 and is received in acomplementary threaded part 128 in the cross-bar130 carrying the brakeshoes 132. Two guide bars 134 are shown to extend rearwardly from crossbar 130, being received in guides 136 secured to the shaft 138 of therear set of wheels 16. The cross-bar 130 is formed with cutouts 140 topass over the flanges 142 of wheels 16, so that the shoes 132 may becomeoperative upon the face 144 of said wheels.

The wheels 16 are mounted on shafts 138, the intermediate portions ofwhich are formed of square cross sections, as appears from Fig. 6. Saidshafts are supported from the bottom 48 by the V-shaped straps 146,detachably secured to said bottom, and having the U-shaped strap 148secured therewithin, and contacting the upper surface of shaft 138 toretain said shaft against vertical movement. The wheels 16 may be madeup in any usual manner to provide the flange 142 guiding and positioningthe wheels on rails 152. A grease cup 154 is mounted in the hub 156 ofsaid wheels for lubricating purposes.

On the side of the car opposite the bracket 108, another bracket 158 ofsimilar construction is secured and has the shaft 160 passingtherethrough to be received in the bracket 162, mounted similarly tobracket 158 at the lower edge of said side. The bevel gear 164 ispositioned at the end of shaft 160, a bevel gear 166 meshing with bevelgear 164 and carrying the end of a stub shaft 168. Said stub shaft isrotatably mounted in a bracket 170, secured to bottom 48 and terminatesin threaded portions 172, adapted to be received in a threaded openingin the depending arm of an L-shaped bar 17 8. Said bar is formed with aplurality of openings 180, which, by rotating shaft 160, are broughtinto communication with similar openings 182 in the bottom of 'a hopper184 having an inclined bottom 186, said hopper receiving sand or similarabrasive ma'teria-l. from a chute 188 secured to the side of the car bya strap 190. The openings 182 in, the bottom of hopper 184 are alignedwith nozzles 192 extending from said hopper and secured in position todischarge sand upon the rails 152,, when desired. Y

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions. of practical use.

As various possible embodiments-might be made of the above invention,and as Various changes. might be madein the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawings is tobe interpreted as illustrative and notin alimiting. sense.
